Area 69, pills, injector, storage update

Added definitions for spawn room position and added an exception for
swim-fly hack detection at this point (players are reported of using the
animation after spawning in at the character creation/login screen)

Moved attach slot definitions to an enumerator.

Renamed "Ammo Box" to "Small Box" to avoid confusion with recent ammo
items. It also now has 4 slots as it's a lot smaller than the "Medium
Box" in physical size.

Replaced an old and unused box type with "Large Box", holds 10 items
total.

Added a number of new crafting items that are currently used to craft
the "Hack Device" to hack keypads, these new items will also be seen in
the future in other item combination sequences for more crafting
options.

Added plant pot because why the hell not. (Possible drug growth
mechanic)

Added infection from eating certain uncooked foods, this results in
frequent screen shakes and faster hunger rate until Antibiotics are
taken.

Moved "Drugs.pwn" file to "Player" folder as it's more of an internal
feature rather than an actual gameplay mechanic.

Added "scripts/SSS/UI/Keypad.pwn" which displays a 4-digit keypad to
type codes into, currently in use at Area 69.

Added "canRawInfect" property to food items, this determines if the food
can infect players if not cooked. Current food items that do this are
Hotdogs, Unwrapped Burgers and Meat.

Lowered radio frequency threshold to 0.05Hz.

Added new vehicle data files to "/scriptfiles/vehicles/" folder, these
comply with the new vehicle loading code.

Improved Zipline functionality to support higher player counts and
players with slower connections.

Altered ammunition tin default spawn amounts.

Removed .50 ammo rounds, desert eagle now uses .357 along with the Rifle
and Sniper.

Improved Injector item to be more useful, Adrenaline now stops all
knockouts (apart from taser) gives slow health regen and stops any form
of camera shake. Morphine gives camera shake, health regen and slows
down bleeding. All injector effects now last 5 minutes.

Improved Pills item to be more useful, replaced Aspirin with Antibiotics
which cure infection, Painkillers now give 10HP on use, remove screen
darkness and stop the below 40HP random knockouts, all pill effects now
last 5 minutes.

Moved vehicle repair back to the original values, finishing the
screwdriver part of the repair sequence now removes all smoke again.

Fixed random low health knockouts and balanced timings.

Updated loot spawn indexes for ammo, weapons and some survival gear, all
of this is now far more rare.

Decreased chance to bleed after blunt melee attacks.

Added infection to player character data saving array.

Dramatically decreased the rate at which vehicles take damage, it now
takes a lot longer to destroy a vehicle from gunfire or crashing.

Restructured a lot of code in the player vehicle update function.

Fixed a bug where a throwable weapon would remain in a player's hands as
an item after throwing.

Added more water areas for IsPlayerInWater util function.
